LEAD AND CRAYoN HOLDER.

`SPECIFICATION forming part of Letters vllatent No. 265,894, dated October 10, 1882.

Application filed May 27, 1882.

To all whom @t may concern Be it known that I, RICHARD W. UHLIG, of `the city, county, and State of New York, have invented certain new and useful Improvements in Lead and Crayon Holders, of which the following is a specification.

My invention has reference to a stop gage or check, whereby the loose lead of a lead or crayon holder is prevented from dropping beio youd a predetermined distance from the sheath orcase. lhisfeaturcisnotherebroadlyclaimed hy me. My present specification is directed to a convenient and effective form of inechanical instrumentality for accomplishing the rerlhis instrumentality is one which clasps the lead, and which, asit drops with the lead, brings up against astop or shoulder on some suitable part ot' the holder, so as to arrest the fall of the lead when the point of zo the latter projects a predeterminedv distance beyond the point or front end of the pencil. A lead clasp or check thus operating is not here broadly claimed. The feature to which this specification is directed is one which permits the clasp to be released from the lead, and opened or expanded whenever desired, so as to leave a free and unobstructed passage for the lead'into or out from the. lead-tube, thus allowing a lead to he introduced into or with- 3o drawn from the holder without diiiiculty.

The preferred embodiment of my invention is represented in the accompanying drawings, which I shall now proceed to describe.

Figure l is a longitudinal central section of the holder-with the parts in the position which they assume when the lead is entirely within the holder. Fig. 2 is a sectional elevation of the same with the parts in the position they assume when thejaws have been pushed forward 4o far enough to release the lead and allow it to drop. Fig. 3 isa like view, with the lead-tube pushed far enough forward to cause the clasp or check-ring to expand and quit the lead.

ln this embodiment of my invention the holder is one resembling the ordinary automatic77 pencil now in the market.

Ais the sheath, terminating in the usual tip or nozzle. B is the longitudinally-movable lead-tube, havinglead-graspingjaws b, and se- 5o cured at its rear end to the pressurecap O, and

(No model.)

D is the retracting spring. This type of pencil is well known and requires no further explanation.

W'ithin the tip a, and loosely surrounding the lead-tube, is the lead clasp or check c,which is provided with a laterally-projecting iiange,

d, or its equivalent, which, by bringing up against a shoulder or stop, c, on the inside of the tip, prevents movement beyond that point by the check-ring; and also with springfingers 6o j', which extend through longitudinal'slots g in opposite sides ot' the lead-tube, and lightly clasp between them the lead x therein. These constitute the mechanical features oi` my contrivance. 6

The operation is as follows: When the lead is withdrawn inside the pencil the parts are in the position shown in Fig. l, the clasp being'in the rear part ofthe tip, and the jaws. b

being closed to prevent the lead from dropping 7o out. By pushing forward the lead-tube far enough to permitthejaws to expand sufficiently for the lead to pass, the lead, carrying with it the clasp, drops down and out from the pencil until the flange d of the clasp brings up against the shoulder c of the tip and stops the lead at the time its point projects the proper distance out from the pencil, as indicated in Fig. 2. lfpressnre be now removed from the press ure-cap, the retracting-spring will cause the 8o ,jaws b to close on the lead, and the pencil then is ready for use. lf, on the other hand, it be desired to expand the clasp so as to reinoveit from the lead, the lead-tube is pushed far enough forward (and it has suiiicient range of movement for this) to bring the inclines g at the rear ends of the slots g under and in contact with the spring-fingersj, which latter, as indicated in Fig. 3, are lifted from the lead. Thelead-passage is, under these conditions, as 9o open and unobstructed as that of the ordinary automatic, and a lead can be introduced into or withdrawn entirely from the. holder without impediment. It is manifest that various forms ot' lifters 95 other than y may be employed, this being determined by the circumstances ofthe case, the particular kind of lead clamping or grasping contrivance employed, and the kind of mechanism employed to operate that device for the Ioo purpose of causing it to release its hold on the lead. In this connection I remark that While I have shown my invention as applied to the regular automatio pencil it is also applicable to the many varieties of the same that have from time t0 time been patented, and the form and arrangement of what I have termed the check-ring or clasp7 may be varied considerably without departure from my invention, the main feature of which is the combination, with the clasp, of a lifting or expanding eontrivance operated from the exterior of the pencil to cause the clasp to release the lead, and to leave the lead tube or passage unobstructed Whenever desired.

I therefore claim as new and of my invention- 1. The lead clasp or check movable with the lead, in combination with the lifting or expanding contrivance, substantially as and for the purposes hereinbefore set forth.

2. Theleadelasporcheck,consistingofaring; loosel5T encircling the lead-tube, and provided With a stop lip or flange, and with spring-fingers Wh ich clasp between them the lead through the slotted lead-tube, in combination with the lead-tube,longitudinallymovable andprovided with lifting-surfaces, and lthe ease or sheath provided with a stop or shoulder to co-Operate With the flange on the check-ring, substantially as hereinbef'ore set forth.

In testimonywhereofl have hereunto set my hand this 26th day of May7 1882.
